E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine the added effect of oral ondansetron to care-as-usual (including ORT) (CAU) on persisting vomiting within the first 4 hours after presentation at an out-of-hours primary care service (OHS) in children aged 6 months to 6 years with acute gastroenteritis. |
|
E.2.2 | Secondary objectives of the trial |
Moreover, we intend to evaluate the predictive value of patient characteristics and symptoms for the risk of dehydration in a population of children at risk for dehydration. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Aged 6 months to 6 years; 2. At least four reported episodes of vomiting or diarrhoea during the last twenty-four hours preceding presentation 3. At least one reported episode of vomiting within the four hours preceding presentation; 4. Diagnosed with AGE by a general practitioner at the OHS. 5. Parental written informed consent. |
|
E.4 | Principal exclusion criteria |
1. Use of anti-emetics in the previous 6 hours; 2. Known renal failure or hypoalbuminemia (as this could affect the assessment of hydration status); 3. Known diabetes mellitus or inflammatory bowel disease (as this could increase the risk of a complicated course); 4. A history of abdominal surgery, with suspected recurrence of original abdominal symptoms or strangulation ileus explaining current symptoms, according to the general practitioner. 5. Known sensitivity to 5-HT3 receptor antagonists; 6. Known prolonged QT interval; 7. Current use of QT prolonging medication; 8. Previous enrolment in the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
The number of children with persisting vomiting during the first 4 hours after inclusion. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
We will evaluate the primary endpoint when the study ends (estimated in 2018) |
|
E.5.2 | Secondary end point(s) |
Cessation of vomiting, the number of vomiting episodes during ORT, referral rate, the proportion that required intravenous rehydration, the proportion hospitalization, quality of life and healthcare use and costs |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
We will evaluate the primary endpoint when the study ends (estimated in 2018) |
